Invest 1.695 billion yuan! Construction of methanol air compression project supporting 1.3 million tons of coking capacity at Xinjiang Zhongtai Coal Coking begins

Thread Content

On March 29, Zotai Coal Coking held the groundbreaking ceremony for the new 200,000 tons per year methanol production facility equipped with electric air compressors, marking the official start of construction for this project. This project relies on existing utility systems for technical upgrades. A new set of electric air compressor units with a capacity of 55,500 standard cubic meters per hour (on a dry basis), along with associated systems, will be installed; this includes a compressor building, electrical control systems, as well as ventilation, dust removal, and fire protection facilities. At the same time, the existing cooling water pipelines, air inlet and outlet pipelines, etc. are optimized and upgraded to encourage enterprises to convert fuel resources into raw materials for methanol production, thereby improving resource utilization efficiency. Compared to traditional steam-driven systems, electric air compressor units offer advantages such as rapid startup, high efficiency, low noise, and easy maintenance. At the same time, it can effectively prevent the impact of shutdowns and maintenance of the main process units and steam boilers on the air separation system, ensuring the long-term safe and stable operation of the methanol plant. Upon completion of the project, it is expected to save 16 million standard cubic meters of coke oven gas per year. The gas obtained as a result can be used as a raw material for methanol production, enabling the manufacture of over 8,150 tons of high-purity methanol. Furthermore, each maintenance session can reduce the startup time by 2 days; this results in annual cost savings of 7.8222 million yuan, a reduction in energy consumption of 7,280.61 tons of standard coal, a decrease in carbon dioxide emissions by 19,000 tons, and savings of 591,400 tons of recycled water. This achieves both the goals of energy conservation and carbon reduction as well as efficient use of resources. The construction period for this project is 7 months. During the construction period, the company will strictly adhere to the principle of \"simultaneous implementation of three aspects\" in project construction, closely monitor the quality and progress of work, and strengthen on-site safety inspections and supervision to ensure that the project is completed and put into use on schedule. It aims to create a model project for industrial energy conservation and carbon reduction in southern Xinjiang, taking practical actions to implement the \"dual carbon\" strategy and promote energy savings and carbon reduction in the industry. Project Overview: Zhongtai Coal Coking is the first coal chemical enterprise in Baicheng County, Aksu Region, Xinjiang, to use coke oven gas to produce methanol. The 200,000 tons per year methanol production facility based on coke oven gas is a supporting project for the 1.3 million tons per year coking plant and the 600,000 tons per year coking plant. Through processes such as precise desulfurization, conversion, syngas compression, methanol synthesis, and methanol distillation, the remaining coke oven gas from coking is converted into methanol. Once the project is completed and put into operation, it will be able to consume 432 million cubic meters of excess gas from coke ovens each year, making effective use of 250 million cubic meters of hydrogen resources, thereby reducing carbon dioxide emissions by 39,500 tons. In addition, the project can produce 200,000 tons of refined methanol per year, generating an annual output value of 440 million yuan and profits and taxes of over 50 million yuan; it will also create more than 150 job opportunities in Baicheng County. Once the project is put into operation, it will further facilitate the transformation of local resources with advantages, boost the economic development and structural adjustment of Baicheng County, and achieve simultaneous gains in terms of environmental protection and economic benefits. Zhongtai’s coal coking project with an annual capacity of 1.3 million tons is equipped with the first 6.25-meter ramming coke oven in Xinjiang region. It uses imported integrated ramming machines, and is accompanied by a coal preparation system, dry quenching facilities, coke treatment systems, gas purification facilities, as well as utility and auxiliary facilities. The investment in this project amounted to 1.695 billion yuan, and it began producing coke on June 1, 2019.
